OK so lets try to harness this enthusiasm.
First welcome to the forum. This is a great resource for 3D printing.
Secondly PLEASE delete your redundant posts. Be patent when posting. Do no be eager to hit the submit button multiple times.
We can share tips but open ended questions are difficult to answer.
So make a list of specific questions an we will do our best to help.
Do you have printer?
And before you jump in make sure you have the skills to operate a 3d printer.
Mechanical skills
electronic troubleshooting skills
computer skills the ability to modify and load firmware.
dogged dedication the ability to not quit when (not if) things go sideways.
3D printing can be a rewarding hobby and you can get started for around $ 400 US
But this is not a sport for the faint of heart.
hope this helps
